PROBLEM TO BE SOLVED: To provide a transformer capable of securing an insulation distance between a primary-side coil and a secondary-side coil surely in simple structure and also attaining further downsizing.SOLUTION: In the transformer, on an outer surface of a double-end flange 2a of a bobbin 2 around which a primary-side coil 1 is wound, a secondary-side coil 3 is disposed, respectively, and a core 6 is disposed that forms a magnetic path by surrounding the primary-side coil 1 and the secondary-side coil 3. Lead-out parts 3a and 3b of the secondary-side coil 3 are led out to an outer peripheral side of the primary-side coil 1, respectively. In an outer peripheral portion of the primary-side coil 1 confronting the lead-out parts 3a and 3b of the secondary-side coil 3, a first spacer 11 in the shape of an arcuate plate is provided along the outer periphery of the primary-side coil 1.SELECTED DRAWING: Figure 1 |
